VALVE ATTACHMENT FOR FIRE PLUGS.

Specizication of Letters Patent.

Patented Jan. 3, 1922?.

Application filed October 23, 1919. Serial No. 332,707.

To all whom it may concern Be it known that 1, CHARLES F. Sonunrr's, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, has invented certain new and useful Improvements in a Valve Attachment for Fire Plugs, of which the following is a specification.

substantially as shown and described and 7 standard plugs.

particularly pointed out in the claims.

In the accompanying drawings, Fig. 1 is a side elevation of a fire plug of a common type with my attachment engaged thereon. Fig. 2 is an enlarged sectional elevation of the attachment alone, as an article of manufacture and sale. Fig. 3 is an end view thereof. All the other views are details in which Fig. 4; is a cross section of the rub-= ber gasket or ring adapted to the interior of the collar; Fig. 5 a sectional elevation of the faucet body; Fig. 6. a sectional elevation of the collar which connects with the plug; Fig. 7 is a view of the valve and its stem with the valve sectioned; Fig. 8 is a sectional elevation of a tubular plug serving as a support for the valve and stem, and Fig. 9 a sectional elevation of the cap for said plug having an extension to house the end of the valve stem. Figs. 10 and 11 show amodification in which the faucet body, Fig. 11, and the flange therefor, Fig. 10, are made in separate pieces.

The fire plug embodiment P shown in Fig; 1 for the purposes of this description may be accepted as the standard street plug now generally in use and with which this attachment is designed to connect, but connection may be made with any other medium of supply adapted to receive the attachment, and said plug is to be understood as having the usual internal valve mechanism controlled through the stem 2, projecting through its top but not otherwise shown herein. The plug also has the usual tubular side extension or neck 3 with which hose connections are adapted to be made in such Practically, my invention begins at this point, and comprises the collar c as the basic element of the attachment.

This element or part substitutes for the cap usually employed to close the side extension 3, and the collar also has lateral projections or arms 4 such as employed on the cap to rotate it on its internal threads 5. But a distinguishing feature in the present collar compared with the cap is in the use of an annular inwardly-extending flange 6 forming a bearing or seat for the relatively large and wide flange 7 at the base of the faucet body 5. The faucet body flange 7 has a rabbet or recess 8 about its edge seated within the collar flange 6, and a rubber or other sealing ring or gasket 9 is interposed between flange 7 and the end edge of neck 3 so that when the collar is turned and screwed to its maximum on said neck a water tight jolnt or seal is formed between the said parts.

The said faucet body in addition to having the relatively large flange 7 at its base to make connection with the collar is also provided with a valve seat 10 interiorly at its middle adapted to be occupied by the valve 4) on the end of the valve stem 12, and said body has an internal thread 13 in its outer portion into which the valve supporting plug 14 isscrewed by a thread about its inner portion. The valve stem extends diametrically through this plug into the valve body and has a quick screw thread 15 in the said plug to open and close the valve and a packing nut or cap 16 is screwed onto the outer end of said plug with the valve stem packed thereon and which has a tubular extension 17 forming a housing for the extremity of the valve stem and into which a suitable wrench can be inserted to turn the said stem and valve to opening and closing of said flange will depend on the size of the opening through collar with which it makes working engagement. As to this feature, it may be observed that, in any event, the opening through collar 0 which now is limited by the internal flange 6, must be large enough to introduce the faucet body with its side extension or nozzle it through the same from the inside up to the flanged portion 7, Fig 5, and hence the said opening could not be much reduced relatively and receive the said body without making the nozzle n removable or making the body '0 and its flange 7 separable, as in Figs. 10 and 11.

The' terms or words fire plug in the claims is to be understood as comprehensive enough to include any of the usual water supply connections to which hose may be attached for extinguishing fires or for flushing the streets.

What I claim is:

1. A valve attachment for fire plugs, comprising a screw collar having lateral projections and an inturned flange, and a relatively small faucet body provided with a round flat base flange of relatively large diameter corresponding to the diameter of the flange on said collar, said body having a short screw-threaded nozzle at one side, and said collar being freely separable from said body.

2. A valve attachment for fire plugs, commeans to make a fluid-tight joint between 40 said parts and the said fire plug.

3. A fire plug having a threaded extension for a. large fire-hose coupling, in combination With an internally-threaded collar to connect with said extension, a small faucet body having a relatively large flat base flange in union coupling engagement with said collar, a sealing ring seated against the fiat side of said flange, a nozzle at one side of said body having a screw-threaded extremity, and a valve t close the passage through said nozzle.

4:. A valve attachment for fire plugs, comprising a collar, a valve body having a small Waterway and a relatively large base flange and a lateral discharge nozzle, said body and nozzle being of less size than the opening in the collar to permit separability of said parts, and a valve member within said body adapted t regulate the outflow of water through said nozzle.

Signed at Cleveland, in the county of Cuyahoga, and State of Ohio, this 8th day of October, 1919.
